Definitions

  • the present invention relates to a cutting pliers, which has been specially designed for plastic pipes, such as PVC, PP, PX, etc. tubes, as well as for multilayer pipes and the like.
  • the object of the invention is to achieve a pincer which, in addition to being structurally very simple, easy to assemble and consequently economical, allows a very easy replacement of its blade without the need to disassemble the pincer, specifically by removing a pin.
  • the invention thus falls within the scope of cutting tools for plastic pipes.
  • Pliers are known for cutting plastic tubes based on two articulated arms, scissor type, to one of which a blade is joined laterally that in the closing of the pliers and with interposition of the corresponding tube, advances towards an existing bearing in the another arm, producing the cut.
  • This type of pliers presents a problem with a double slope, on the one hand the blade always remains in a direct situation accessibility, which implies a permanent risk of accident by cutting, and on the other hand the blade is rigidly attached to the corresponding arm with the collaboration of a pair of screws, which is a slow task of replacing the blade, since it is necessary remove the aforementioned screws, remove the used blade, place the new blade and assemble and tighten the aforementioned screws.
  • the cutting pliers for plastic tubes proposed by the invention fully and satisfactorily solve the problems described above, in the two aspects mentioned, so that in addition to keeping your blade retracted in an inoperative situation, it allows an easy and rapid disassembly / assembly for blade replacement, no need to disassemble any of the scissor arms, no need to act on no screw, exclusively removing a pin, as previously mentioned, maneuver that is obviously extremely fast and simple.
  • the clamp that is recommended is of the type that are constituted by two arms joined together by means of a scissor joint, one of whose peculiarities is that each of said arms is single-piece, so that its assembly is simplified, specifically reduced to the coupling between both pieces in a suitable position so that they are related by its own tilt axis.
  • One of said arms incorporates a window in correspondence with its middle plane, through which the other arm partially penetrates inside.
  • a pin is established as a tilting axis for the blade, and in contrast to said window the outer arm incorporates a groove through which said blade is susceptible to emerge when the pliers are closed.
  • the blade is also tiltable on a second pin, through a roller that rotates on said pin, but with the particular feature that the tilting of the blade with respect to said roller is carried out through an open groove towards one of the edges of the blade, so that the tilting axis of the scissor arms and the two aforementioned pins, form a deformable triangle that gives the blade a planetary movement, specifically a combined movement of translation and rotation towards the cutting edge defined on the outer arm.
  • the openness of the aforementioned blade groove allows that, by removing the pivot or pivot pin for it, said blade can easily be removed from the pliers for replacement.
  • Figure L- Shows, according to a plan view, a cutting pliers for plastic pipes made in accordance with the object of the present invention, in an inoperative situation therefor.
  • Figure 2. Shows a representation similar to the previous figure of the same pincer, now in a situation of maximum opening.
  • Figure 3 shows a similar to that of Figure 2, but in which the arms have been represented transparently to allow visualizing the internal structure of the pliers.
  • Figure 4.- Shows a detail in plan of the blade.
  • Figure 5. Shows, finally, a representation in side elevation of the pin in function of tilting axis for the blade.
  • the cutting pliers that the invention proposes are constituted from two arms (1 and 2), articulated jointly with each other through a pin (3), determining a scissor joint, adopting the arm (1) a ribbed configuration in all its extension, with inwardly oriented concavity, to minimize the amount of material that participates in it, while the arm (2), also grooved in its half corresponding to its handle, It is finished off in a head (4) that in its middle area incorporates a pin (5) in function of tilting axis for the blade (6), which is in turn provided with a hole (7) for access of said pin ( 5), said head being hollow and open towards the inner edge of the arm itself (2), in a sufficient magnitude to allow both the play of the corresponding limb of the first arm (1), through the axis (3), as blade tilting (6) during the cutting maneuver, a blade that emerges towards the outer edge of the arm (2), specifically towards the classic
  • the tilt axis (3) of both arms, the tilt pin (5) for the blade (6) and the pin assembly (9) and the corresponding roller associated therewith, form a deformable triangle that forces the blade to swing, while turning, so that the attack on the tube to be cut occurs at all times in the most suitable direction.
  • the blade can be easily removed for replacement, without pulling the internal end of it, that is, the end corresponding to the closed bottom of the groove (10).
  • said pin (5) in order to avoid accidental or unwanted decoupling of said pin (5), it is flush with the head (4) on one of the faces thereof, and occupies the bosom of a recess (11 ) of the other side of said head, so that it is accessible without protruding outside, said pin also having a tiny retractable ball (12) against the tension of a spring, through which it is locked in normal situation of work.

Abstract

Selon l'invention, avec deux bras unis et articulés de type ciseaux au moyen d'un axe (3), le bras extérieur plus large (2) reçoit avec un caractère amovible une broche (5), à proximité dudit axe de basculement (3), en fonction de l'axe de rotation de basculement pour la lame (6), laquelle est liée de plus avec l'autre bras (1) au moyen d'un rouleau basculant ou d'une broche (9) établie sur celui-ci, jouant dans une rainure ou un orifice (10) de la lame, considérablement élargie et ouverte à son extrémité intérieure, de manière à ce que le remplacement de la lame soit extraordinairement rapide et simple, étant donné qu'il suffit de démonter la broche (5) pour que la lame (6) puisse être libérée et puisse se déplacer jusqu'à ce qu'elle quitte le rouleau associé à la broche (9) par ladite rainure (10).
